NEEDLE TI-IREADER, ESPECIALLY SUITABLE FOR SEWING MACHINES Filed Oct. 27, 1961 INVENTOR. CARL E. OARLSEN United States Patent 3,115 996 NEEDLE THREADER, ESPECIALLY SUITABLE FOR SEWING MACHINES Carl E. Carlsen, 867 3rd Ave., New York, N.Y. Filed Oct. 27, 1961, Ser. No. 149,149 1 Claim. (Cl. 223-99) This application is a co-pending application of my application, Ser. No. 811,596, filed May 7, 1959, and for which Patent No. 3,022,927 has issued Feb. 27, 1962.

The object of this invention is to make a needle threader of the push-hook type which is particularly suitable to be used for sewing machines where the needle is so arranged that the eye is from left to right of the operator and the thread is intended to be inserted from left to right also.

The said needle threader has in it similar threading features as those described in my previous application, but it has also its new features that are to be used for this type of sewing machine, as it will permit, by using the right hand, to thread the needle from the left side without the user shifting his position and using one hand only.

The user threads the needle threader holding it conveniently before him and then using his right hand for holding the threaded needle threader, holding the thread tight with his right band also.

He then proceeds to insert the push-hook with the thread into the eye of the needle from the left side; releasing then his tight hold on the thread, the loose thread will now slide down from the heel of the threader, leaving the latter free to be removed, while leaving the loop of the thread in the eye of the needle.

In the drawing:

FIGURE 1 is a side elevational view of a threaded needle threader, ready for use.

FIGURE 2 is a top plan view of my invention; while FIGURE 3 is a view similar to FIGURE 1, but with the thread removed.

Referring more particularly to the drawing, the numeral indicates the handle of a needle threader, while the numeral 11 shows a cut+out in the handle so as to leave space for the threading member 12 which is provided with a hook 13.

In said FIGURE 1 is shown, as broken off, a small part of a sewing machine proper, with the sewing machine needle 14, which has the conventional eye 15.

The handle is formed with a substantially rectangular recess 16 which serves to change the direction of the thread so as to permit holding both the threaded needle threader and the thread tight with one hand only during threading of the needle.

The said recess 16 is tapered downwardly as at 17, so that upon loosening the thread the latter will slide 01f the handle and fall down and away from the needle threader due to said tapered portion.

What I claim as my invention, and desire to secure by Letters Patent of the United States, is:

A push-hook needle threader for sewing machine needles, comprising an elongated handle formed with a cutout therein, longitudinal of said handle a threading member supported adjacent and at one end and on one side, and being integral with said handle, said threading member having a free end projecting longitudinally and parallel in to said cut-out for engagement with a needle, and the free end of the threading member having a cut-out hook for holding a thread at its end; said cut-out hook facing the handle-part of the needle threader, said handle being formed with a substantially rectangular recess at one end thereof, whereby to hold and to change the direction of the thread, and a tapered portion forming part of said recess, whereby to permit the thread, when loosened, to slide off and fall away from said needle threader.
